=============================================

|
|
keybrd library is an open source library for creating custom-keyboard firmware.
|
2016-07-18 02:26:00 +00:00
|
|
|
The keybrd library allows keyboard designers to develop and publish their firmware simply as possible.
|

|
|
|
|
|
|
|
|
keybrd library can support any keyboard configuration:
|
|
|
|
|
* one-piece
|
2016-07-18 02:26:00 +00:00
|
|
|
* split with shift registers
|
2016-05-09 14:05:08 +00:00
|
|
|
* split with I/O expander
|
|
|
|
|
* single-layer
|
|
|
|
|
* multiple-layer
|
|
|
|
|
|
|
|
|
|
Multiple-layer keyboards can write symbols without using the shift key:
|
|
|
|
|
|
|
|
|
|
~ ! @ # $ % ^ & * () _ {} | < > : ?
|
|
|
|
|
|
|
|
|
|
keybrd library leverages the Arduino environment to create keyboard firmware.
|
|
|
|
|
The Arduino development environment is free, and easy for novice programmers to setup and learn.
|
|
|
|
|
|
2016-07-18 02:26:00 +00:00
|
|
|
The keybrd library has been tested on Teensy LC, Teensy 2.0, 74HC165 shift registers, and PCA9655E I/O expander.
|
2016-07-21 20:20:07 +00:00
|
|
|
The resulting keyboard firmware is compatible with standard USB keyboard drivers.

> The keybrd library is in Beta testing. The public API should not be considered stable.

A [minimal keybrd sketch](/tutorials/keybrd_1_breadboard/keybrd_1_breadboard.ino)
|
|
|
|
|
is 40 lines of code for a 4-key keyboard.
|
2016-05-09 14:05:08 +00:00
|
|
|
The sketch is small because the keybrd library takes care of the low-level details.

It runs the breadboard keyboard in this picture.

keybrd_DH and its instantiation files contain about 800 lines of code.
|
|
|
|
|
It emulates the DataHand keyboard.
|
|
|
|
|
The layout has 52 keys, 4 layers, 6 sub-layers, 2 matrices, 8 LEDs, and blinking LEDs.
